Peter Grant – Subsurface Advisor, Geologist and Geophysicist

Peter has over 45 years of experience in the upstream oil and gas industry specialising in, exploration and international E&P business development. 

He has extensive work experience in Africa, South East Asia, Middle East, South America and Australasia, and has led successful teams that have made discoveries in the UK, Australia, Algeria, Libya, Sierra Leone and Mauritania.  Peter’s experience base is founded in geoscience but has extensively augmented his expertise in corporate strategy, business development, commercial negotiations and portfolio management through his roles such as Exploration Manager for Africa and Middle East for BHP Petroleum, and through senior roles in Woodside Energy as International Exploration Manager, General Manager International, and General Manager International Ventures.

Peter established International Energy Solutions, a strategic advisory company for the energy industry and has recently advised clients on growth projects in sub Saharan Africa, China and South East Asia, both petroleum and coal seam methane related. He also provides commercial and political risk advice and has conducted numerous oil and gas training seminars.

He has a BSc (Hnrs) in Geology from Nottingham University (UK).

He is currently a non-executive Director for ASX listed Botala Energy Ltd and is technical advisor to both Transborders Energy Pty Ltd and deepCstore Pty Ltd.

He was AAPG President for the Asia Pacific region from 2015 to 2017 and a member of the AAPG Advisory Board for the same period. He is currently vice president for the Asia Pacific region. In 2021 he was awarded the prestigious AAPG Vladsimila Dvorakova International Service award for work undertaken for the AAPG in the Asia Pacific region.

Unlocking Offshore CO2 Storage in Australia With A Floating CCS Development Hub

Presented by Daein Cha and Peter Grant (DeepCStore)


Carbon capture and storage (CCS) is central to a clean energy transition. According to the UN’s IPCC and IEA, CCS needs to attain a global CO2 reduction capacity of ~4 billion tonnes per annum by 2050 to achieve Paris Agreement targets (IEA, 2020). To date, only 30 large scale CCS facilities are operational worldwide, totalling 42.6 million tonnes per annum of CCS capacity (Global CCS Institute, 2022). A massive number of new projects are needed.

Australia has a potential CO2 storage capacity of 434 billion tonnes, with 316 billion tonnes (73%) residing in offshore oil and gas fields and aquifers (Carbon Storage Taskforce, 2009). The APAC region also provides significant additional COstorage capacity.

A key constraint to unlock the potential CO2 storage capacity in Australia and the APAC region is that the CO2 storage sites and emitter sources are not necessarily located close by. Since most CCS projects considered to date use pipeline transportation, this limits the number of developments to those that have the emission sources and storage sites in proximity.

By utilizing the Floating CCS Hub development concept, which includes liquefied CO2 carriers and floating CCS hub facilities, CCS can be provided to a broader range of emission sources. The transportation cost using liquefied CO2 carriers is not as sensitive to transport distance as pipelines, which have a linear relationship between distance and cost. Liquefied CO2 carriers and floating CCS hub facilities also minimise development constraints related to pipeline distances and land use, and enable replicability and scalability to unlock multiple offshore CO2 storage sites for CCS in Australia and the APAC region.
